Thirty-one consecutive patients (18 boys, 61%) who underwent the implantation of a Medtronic Kappa 901 pacemaker were enrolled. Mean age was 7.5 ± 6.2 years (median 6.5, range 1 day to 24 years).

FAILURE of the myocardium to respond to an electronic pacemaker with implanted electrodes, because the threshold to electric stimulation is abnormally high, is known to occur occasionally. 1, 2 In all ...

A novel leadless cardiac pacemaker demonstrates stable performance and reassuring safety over 1 year after implantation, according to results from a small study published in the April 21, 2015, issue ...

The EnRhythm pacemaker system was found safe and effective in patients undergoing magnetic resonance imaging, according to trial results presented this morning at Heart Rhythm 2009. The pacemaker ...

Transvenous leads that deliver pacing therapy to the heart via a subcutaneous pacemaker cause complications in approximately 12.5% of patients implanted with the device. In a new study published in ...

A leadless cardiac pacemaker showed "good safety and reliable function" during the initial six months of follow-up in the LEADLESS II study, investigators reported. A leadless cardiac pacemaker showed ...

Pacing threshold varies during the 24 hours in children (Fig. 2). This variability is low, not exceeding 0.2 V (0.03 ± 0.01 V), so it is unlikely to affect pacemaker programming. There were no ...
